Storage & Handling
- Product-Specific Storage
This product is supplied as a freeze-dried material. Keep the original container sealed and follow the storage condition shown on the product label or available documentation.
Follow the format-specific instruction shown above. Product-specific label or documentation requirements take priority over the general handling guidance below. - Keep the Original Container Sealed
Until the material is needed for laboratory work, keep it in its original sealed container. Protect it from moisture, unnecessary light exposure, and avoidable temperature fluctuations. - Inspect the Package on Receipt
Check the container, seal, and packaging for visible damage, condensation, or signs of a temperature excursion. Record any issue before placing the material into laboratory storage. - Document Laboratory Handling
Record the material name, batch information, receipt date, storage location, and relevant handling conditions according to your laboratory’s procedures. - After Opening or Preparation
Once the original sealed state changes, follow the product documentation and your laboratory’s validated protocol. Clearly label any prepared material with the preparation date, composition, and applicable storage condition. - Avoid Unnecessary Temperature Cycling
Minimize repeated warming and cooling. Avoid repeated freeze-thaw cycles when frozen storage is required by the applicable protocol. - Use Material-Specific Conditions
Storage requirements can differ between lyophilized, liquid, and prepared materials. Do not apply one temperature, solvent, or stability period to every product.

Frequently Asked Questions
Find answers to common questions about this product, its research context, Certificates of Analysis (COAs), ordering, and laboratory use.
What is PT-141 typically studied for?
Researchers most often study PT-141 for melanocortin-mediated behavior, arousal-related neurobiology, and central nervous system receptor signaling. The compliant way to present it is to emphasize the receptor class and research context, not to market it with direct lifestyle or sexual-performance claims.
What is PT-141?
PT-141, also known as bremelanotide in the scientific literature, is a melanocortin receptor agonist. It is very different from extracellular-matrix or growth-hormone peptides because its main research interest is neurobehavioral melanocortin signaling. It is a research peptide in the melanocortin class.
What are melanocortin peptides?
Melanocortin peptides are a family of signaling peptides derived from the precursor protein proopiomelanocortin (POMC). The family includes α-MSH, β-MSH, γ-MSH, and ACTH, along with a number of synthetic analogs developed for research purposes, such as Melanotan I, Melanotan II, PT-141, and others.
Melanocortins are studied in connection with pigmentation pathways, energy-balance signaling, and melanocortin-receptor subtype selectivity, depending on which receptor subtype is engaged. All melanocortin-class compounds offered by Prima Vora are lyophilized research materials intended solely for in vitro laboratory investigation.
What is the melanocortin receptor system?
The melanocortin receptor system is a family of five G protein-coupled receptors designated MC1R through MC5R. Each subtype has a different tissue distribution and research-studied function: MC1R is associated with melanocyte biology and pigmentation, MC2R with adrenal cortex signaling, MC3R and MC4R with central nervous system pathways related to energy balance, and MC5R with exocrine tissues.
Research on melanocortin peptides is largely organized around which receptor subtypes a given peptide preferentially engages. This receptor selectivity is a key variable in how these compounds are studied in the laboratory.
How do α-MSH and related peptides fit into this family?
α-MSH (alpha-melanocyte-stimulating hormone) is a 13-amino-acid peptide derived from POMC and is one of the best-studied members of the melanocortin family. It is investigated primarily in the context of MC1R signaling and pigmentation research, but it also interacts with other melanocortin receptors at varying affinities.
Synthetic analogs such as Melanotan I and Melanotan II were developed to study more stable or receptor-selective variants of the natural α-MSH sequence. These analogs retain the core structural features of α-MSH while differing in their stability and receptor preference, which makes them useful reference compounds in melanocortin-system research.
